Privacy Policy

1Who we are

Lanefold is a stopwatch and lap timer for coaches, developed by Zydeno. It times a group of athletes lane by lane, records laps and splits, runs interval sets, and can use the phone’s camera as a finish gate that times athletes as they cross a line. This policy explains what the app keeps on your phone, what the camera does, how exports work, and what happens if you choose to contact us at [email protected].

2What this policy covers

This policy covers the Lanefold Android app. It does not cover the text-to-speech engine on your phone, the apps you share files to, document or cloud storage providers, or the browser and e-mail app you use. Their own terms and privacy policies govern the data you give them.

The app works without an account or an internet connection. The app has no ads and no analytics.

3What the developer does not collect

The app does not send the developer athlete names, groups or bib numbers, times, laps, splits, placings, notes, interval plans, camera frames, finish images, exported files, settings or device information. It has no account registration, no advertising SDK, no analytics SDK and no third-party crash reporter. It does not request internet, location, microphone, contacts, phone, notification, photo-library or storage access.

We do not receive, sell or share your in-app data, use it for advertising or train models on it. Lanefold never asks for your own name or contact details.

4What is stored on your phone

Lanefold keeps its working data in Android app-private storage (a local database, files and a preferences store). Depending on how you use the app, this includes:

• Athletes: the name you type, an optional group and an optional bib number.
• Sessions and heats: date and time, the event (distance, splits, start type, timing method), lanes, and every mark: the time measured by the phone’s clock, how it was taken (tap, swipe, volume key or gate), edits together with the earlier value, and DNS, DNF or DQ codes. Placings and best times are worked out from these marks.
• Gate crossings and finish images (see Finish images).
• Interval plans and the results of the sets you run.
• Notes you add to a session.
• Settings: language, each unit choice, paper size, hand-time comparison, sounds, haptics, starter voice, gate frame rate, how long finish images are kept, and similar preferences.

All timing, ranking, comparisons, pace calculations, gate analysis and file generation run on your phone. This data is removed when you uninstall the app or clear its storage.

5Camera and the finish gate

The camera is the only sensitive permission Lanefold asks for, and it is optional. Lap and finish timing by tap works without it.

• Asked in context. The app explains what the camera is for before Android shows its permission prompt, the first time you open the gate or reach the gate step of the introduction. If you refuse, the gate shows how to allow it later; you can withdraw the permission at any time in Android Settings.
• Foreground only. The camera runs only while the Gate screen or the accuracy check is open and visible. The screen shows the live view of the line and whether the gate is armed. When you leave that screen, switch to another app or turn the screen off, the camera is released and the gate pauses. It does not re-arm by itself; you tap Arm again. Lanefold has no background or foreground service that uses the camera.
• Frames stay in memory. The app reads the brightness of narrow bands across the finish line in each frame to detect a crossing and to measure frame timing, and then discards the frame. It does not record video, does not save photos to your gallery and does not record sound.
• No identification. The gate measures how much of the line is covered, not who crosses it. Lanefold performs no face detection, face recognition or other biometric processing.
• Accuracy check. The accuracy screen uses the same camera to measure the frame rate and timing of your phone. The result is shown to you and stored with your settings; it is not sent anywhere.

6Finish images

For each crossing, the gate keeps one small greyscale image built from the finish line over about a second around the crossing. It lets you check and correct which athlete crossed when. A finish image can show the athletes who crossed, their clothing and bib numbers, and anyone else who passed the line.

• Where. Finish images are stored in the app’s private storage on your phone, linked to the crossing and the heat. They are never uploaded.
• How long. By default, finish images are deleted automatically after 30 days. The time they confirmed is kept. In Settings, Keep finish images, you can choose 30 days, keep them, or not keep them at all.
• Delete now. Settings, Your data, Delete finish images now removes every finish image and keeps all times. Deleting a session or using Delete all also removes its images.
• Exports. Finish images leave the phone only in an export you create yourself, as described in Export, sharing, backup and import.

7Information about athletes and other people

Lanefold is used to time other people, often children and teenagers in school and club sport. The names, groups, bib numbers, times, notes and finish images about them are entered or captured by you: the coach, parent or helper, or the club or school you act for. The developer never receives this information.

You decide what to enter. A first name, initials or a bib number is enough for the app to work. Where data-protection or safeguarding rules apply to you, for example because you time athletes for a club, school or business, you or your organisation may be responsible for this data. That can mean having a lawful reason to record it, telling athletes and parents what you record, and getting consent where it is required, such as parental consent for minors or consent to images. Purely personal or household use may be treated differently in some countries. This is general information, not legal advice; check the rules of your club, school, federation and country.

If an athlete or parent asks you to show, correct or delete what you hold about them, you can do so in the app: edit or remove the athlete, their sessions and their finish images. Ask the person you shared files with to delete their copies too.

8No internet access from the app

The current Android app does not declare the INTERNET permission. It has no backend, no external API requests, no automatic uploads, no remote downloads and no cloud synchronisation. Fonts, sounds and help text are bundled in the app.

Starter voice. The spoken starter commands use the text-to-speech engine installed on your phone. Lanefold passes it only the fixed starter commands. The engine works under its own settings and policy; some engines can use online voices. The microphone is never used.

Links. When you open this policy, the Terms or the support e-mail address, the app hands the address to your own browser or e-mail app. Your browser then visits the site, and the website host can process ordinary web-request data such as your IP address under its own policy. Nothing is sent by Lanefold itself, and a support e-mail is sent only if you choose to send it.

9Export, sharing, backup and import

Results. You can export a session as a result sheet (PDF, A4 or Letter), a spreadsheet (CSV) or text for chats. A file is created only when you tap Export or Share, and it goes through Android’s share sheet to the app you choose, or to the place you pick in Android’s file picker. It contains what you entered: session and athlete names, bib numbers, times, splits, placings and notes.

Finish images in exports. Finish images are left out of the result sheet unless you switch on Include finish images. When you do, the app warns you that finish images show athletes and that you should share them only with people who agreed.

Backup. Settings, Your data, Export everything creates one backup file with your athletes, sessions, marks and settings, and the finish images still on the phone. It is a complete copy of your Lanefold data, including information about the athletes you time, and it is not password-encrypted by Lanefold.

Import. Import a backup reads only the file you select in Android’s file picker. The app checks it on the phone and adds its contents to what is already there. No storage permission is needed.

Your destination matters. A chat app, e-mail app, cloud drive or other recipient receives the file you choose to give it and keeps it under its own policy. This is a transfer you start, not automatic synchronisation. Zydeno receives no copy unless you deliberately send one to support.

10Permissions and device access

Camera is the only runtime permission the app requests (see Camera and the finish gate). Phones without a usable camera can still install Lanefold and time by tap. The app does not request internet, location, microphone, contacts, phone, notification, photo or media, storage-wide, all-files, Bluetooth, exact-alarm or Accessibility-service access, and it runs no foreground service. Android also adds an app-scoped internal permission used by its support libraries; it does not grant access to your personal files or sensors. The advertising-ID permission is removed from the app.

Region. To choose sensible default units, distances, paper size and number format, the app reads your device’s region locally: the country reported by your SIM or network through Android’s standard telephony information (no permission is needed and no phone number or subscriber identifier is read) and the region of your system language. This value is used on the device only and is not transmitted. You can change every unit in Settings.

Other device features. The gate’s alignment hint can read the phone’s motion sensor at a normal rate to tell whether the phone is level; this needs no permission and stays on the device. If you switch on Volume keys, the app reads those keys only while it is open. The screen stays on during a running session. Haptic feedback and sounds can be switched off in the app or in Android.

11Your controls, backups and deletion

You can edit and remove athletes, groups, sessions, marks and notes, delete finish images, change every setting, export a backup, and use Settings, Your data, Delete all data to remove all athletes, sessions, finish images and settings after typing DELETE to confirm. Export a backup first if you want to keep your data.

Automatic Android backup is disabled, and the app’s data-extraction rules exclude both cloud backup and device-to-device transfer. To move your data to another phone, use Export everything and import the file yourself. If the phone is lost or the app’s storage is cleared without a backup, the developer cannot restore your data.

Uninstalling Lanefold or clearing its storage in Android Settings removes its private data. Deleting items in the app does not delete files you exported, copies received by other apps or people, or paper copies; remove those separately.

12Legal bases for processing

Where the EU or UK GDPR, or a similar law such as the Swiss FADP or Brazil’s LGPD, applies, these are the legal bases for the limited processing described in this policy:

The app makes no automated decisions that have legal or similarly significant effects on you, does not build a profile of you and does not process special categories of personal data. It performs no face detection, face recognition or other biometric identification on camera frames or finish images. Athletes’ names, times and finish images stay on your device under your control, and the developer receives none of them.

13How long information is kept

Athletes, sessions, times and settings stay on your phone until you remove them, clear the app’s storage or uninstall the app. Finish images are kept for the period you choose in Settings (30 days by default) and are then deleted automatically. Deleting an item is not a guarantee of forensic erasure of every byte on the device.

Temporary export files may remain in the app’s cache until Android or the app clears them. Files you saved or shared outside the app remain under your control, or the recipient’s, and may outlast uninstallation.

14Your privacy rights

Privacy laws in many countries give you rights over your personal data. Because Lanefold keeps your data on your phone and the developer does not receive it, most of these rights are in your own hands: you can view, correct, export and delete everything in the app (§11) and withdraw permissions in Android Settings. For data you have sent us, such as e-mails, write to [email protected].

EU and UK representative. The individual developer does not process personal data of people in the EU/EEA or the UK except occasional e-mails you choose to send to support. This occasional processing does not involve large-scale processing of special-category or criminal-offence data and is unlikely to result in a risk to your rights and freedoms. Under Article 27(2)(a) GDPR and Article 27(2)(a) UK GDPR, it does not require an EU or UK representative, so none is appointed. Contact us directly at [email protected]; you can also complain to your local supervisory authority.

Rights by region. A summary; the law where you live decides the details.

• European Union, EEA, United Kingdom and Switzerland (GDPR, UK GDPR, Swiss FADP): access, rectification, erasure, restriction of processing, data portability, objection to processing based on legitimate interests, withdrawal of consent at any time, and complaint to a supervisory authority, for example in the country where you live or work (in the UK, the Information Commissioner’s Office).
• United States (California CCPA as amended by the CPRA, and the comprehensive privacy laws of other states such as Virginia, Colorado, Connecticut, Texas and Oregon): to know and access, delete, correct and port personal information; to opt out of its sale or sharing, of targeted advertising and of profiling; to limit the use of sensitive personal information; to appeal a refusal; to use an authorised agent; and not to be discriminated against for using these rights. Notice for California residents: in the last 12 months the developer has not collected personal information through the app, other than e-mails you chose to send us. We have not sold or shared personal information, and we do not use sensitive personal information. Global Privacy Control signals are honoured where the law requires; today there is nothing to opt out of.
• Canada (PIPEDA and provincial laws, including Québec’s Law 25): access, correction and withdrawal of consent; complaints to the Office of the Privacy Commissioner of Canada or, in Québec, the Commission d’accès à l’information.
• Brazil (LGPD): confirmation of processing, access, correction, anonymisation, blocking or deletion, portability, information about sharing and revocation of consent; complaints to the ANPD.
• Japan (APPI): disclosure, correction, suspension of use or deletion; complaints to the Personal Information Protection Commission.
• South Korea (PIPA): access, correction, deletion, suspension of processing and withdrawal of consent; complaints to the Personal Information Protection Commission or the KISA privacy centre. The person responsible for personal information is the developer, reachable at [email protected].
• Australia and New Zealand (Privacy Act 1988, Privacy Act 2020): access and correction; complaints to the OAIC or the New Zealand Privacy Commissioner.
• Other countries (for example India’s DPDP Act, Singapore’s PDPA, South Africa’s POPIA or Türkiye’s KVKK): the rights your local law gives you. Write to us and we will respond in line with it.

How we respond. We answer within one month, or sooner or later where your local law sets another period (for example 45 days under the CCPA), and we may extend it where the law allows. We may ask for information to confirm that a request comes from you. Requests are free unless they are manifestly unfounded or excessive. If we cannot do what you ask, we explain why and how you can appeal or complain.

15International users

Lanefold is available in many countries. The developer does not receive the data you keep in the app, so we do not transfer it anywhere.

If you e-mail us, your message is processed by our e-mail provider and may be stored on servers outside your country. Where the GDPR or UK GDPR applies to such a transfer, it relies on an adequacy decision, on standard contractual clauses offered by the provider, or on the transfer being necessary to answer your request.

This policy is written in English. If a translation is offered, the English version prevails unless your local law requires otherwise.

16Security

Lanefold relies on Android’s application sandbox for its private data. It does not add a password-protected vault or promise encryption beyond what your device provides. Exported result sheets, spreadsheets and backup files are ordinary files.

No device or storage system is perfectly secure. Someone with access to an unlocked, compromised or rooted phone, a backup file or a shared result sheet may read it. Names, times and finish images of young athletes deserve particular care: use a screen lock, keep your phone updated, share files only with people who are allowed to see them, and do not send athletes’ data to support unless it is needed for your request.

17Ads, purchases and future versions

Today. The current version of Lanefold is free of charge, shows no ads, has no in-app purchases or subscriptions, and contains no advertising, analytics or payment SDKs. This describes the app as it is now, not a promise about future versions. Future versions may introduce advertising, paid features, in-app purchases or subscriptions, or other optional services.

If ads are introduced. Ads would be supplied by a third-party ad network, for example Google AdMob. Ad networks typically process your device’s advertising ID, IP address, approximate location derived from the IP address, device and app information and your interactions with ads, in order to show ads, limit repetition, measure performance and prevent fraud, and, only where you allow it, to personalise ads. Ads would also require the app to connect to the internet, which the current version cannot do.

If purchases or subscriptions are introduced. They would be processed by Google Play’s billing system. Google handles your payment details under the Google Privacy Policy. We would receive only what is needed to deliver and verify a purchase, such as a purchase token, the product, its status, the country and the currency, never your full card or bank details.

Before any such change we will update this policy with a new effective date and version, describing what data is processed, by whom, why and how you can control it; update the Google Play Data safety section; mention the change in the release notes; ask for your consent where the law requires it (for example for personalised ads and non-essential access to your device in the EEA, the UK and Switzerland, through a consent tool that meets Google’s requirements); and offer the opt-outs the law requires (for example under US state privacy laws). The change applies only from the app version that introduces it. Data already stored in the app will not be used for advertising without telling you first and, where required, getting your consent. We will not knowingly show personalised ads to children (§18).

18Age limits

Lanefold is designed for coaches, parents and adult athletes. It is not directed to children under 13. Information about young athletes is entered by the adults who time them and stays on their phones. A parent or guardian who believes a child has sent us personal information can contact support to request its deletion. We cannot see or remotely delete data that exists only on someone’s phone; please ask the coach or club that holds it.

19Changes to this policy

We may update this policy when we change the app (including any change described in §17), when the services the app uses change, or when the law changes. The effective date and version at the top of this page show which version applies, and the version history (§20) summarises every change.

For a material change, for example new data leaving your device, ads or purchases, we update this page and the Google Play Data safety section before the app version with that change is published, describe it in the release notes, and ask for your consent in the app where the law requires it. Changes do not apply retroactively to data processed before them. Earlier versions are available on request from [email protected].
